Sanctuary Trail

Overview

Sanctuary Trail is about big-sky prairie—rolling grasslands, pockets of ponderosa pine, and the kind of quiet where you’ll hear wind and prairie dogs more than people. It runs 3.6 miles one way to a junction with Highland Creek, so most hikers do it as a 7.2‑mile out-and-back or set up a car shuttle for a one-way. The park rates it strenuous, but the grades are gentle; the real challenge is exposure to sun, heat, and weather.

Route and logistics

Park at the Sanctuary Trail Parking Area (about a mile north of the Rankin Ridge fire tower turnoff). From the parking area, walk a short way east along the road; the trailhead is on your right. The path trends on a gentle descent through mixed forest and open prairie before ending at the Highland Creek Trail junction. If you don’t want to retrace your steps, stage a vehicle at the Highland Creek parking area for a point‑to‑point day.

What you’ll see

Expect wide-open views toward Buffalo Gap and the Black Hills. You’ll pass through a large prairie dog town—fun, noisy, and very active—and you may encounter bison sign or bison themselves on or near the trail. Keep an eye out for subtle homestead remnants tucked in the grasslands. The tread can fade in tall grass; look for wooden posts (signed as Trail #5 in spots) across the open sections.

Best time to hike

It’s open year‑round, but the sweet spots are spring, early summer, and late fall. Summer afternoons often bring strong thunderstorms and even large hail, and there’s little shade—start early or go late if it’s hot.

Know before you go

There’s no water on the route—carry plenty. Sun protection is essential. Wear enclosed footwear and long pants for ticks and poison ivy. Give wildlife space (at least 25 yards from all animals, much more for bison). Bison sometimes knock over markers; bring a park map and stay alert for posts in the open fields. You may also meet horseback riders along this corridor—yield accordingly.

Who it’s for

Hikers who want a quiet, classic mixed‑grass prairie experience with abundant wildlife and a dash of history. It’s family‑friendly if you manage distance and heat (turn around as needed). If you prefer a shorter sampler with facilities and easier logistics, consider one of the closer prairie loops; if you want more mileage, continue on Highland Creek or tie into the Centennial for bigger days.
